Cut each chicken breast in half crosswise, then cut the larger half again horizontally, creating 3 cutlets. Transfer to a large bowl.
Completely coat the chicken cutlets in the seasoning. Set the chicken aside.
Arrange the bacon slices in a 9x5-inch loaf pan, making sure the bottom and sides are fully covered, and that the strips hang over the sides.
Layer in 4 seasoned chicken cutlets, 2 tablespoons of barbecue sauce, 5 slices of cheddar cheese, 4 more chicken cutlets, another 2 tablespoons of barbecue sauce, the green pepper, onion, 2 tablespoons of barbecue sauce, the red pepper, 5 remaining cheese slices, and the remaining chicken. Then, wrap the overhanging strips of bacon over the top of the loaf.
Sprinkle some more seasoning over the top.
Cover the loaf with foil and bake for 1 hour. Or smoker 4-6 Hours
Remove the foil, drain any excess fat, and bake for another 30 minutes uncovered, making sure the chicken is cooked through and the bacon is brown and crispy.
Remove the bacon loaf from the oven or smoker and turn on the broiler. Invert the loaf onto a wire rack set atop a baking sheet and baste the loaf with the remaining barbecue sauce.
Broil for 5 minutes, until the glaze dries slightly.
